Mobile hyperspectral imaging for structural damage detection
Numerous optical-imaging and machine-vision based inspection methods are found that aim to replace visual and human-based inspection with an automated or a highly efficient procedure. However, these machine-vision systems have not been entirely endorsed by civil engineers towards deploying these …

Application of hyperspectral imaging in pharmaceutical analysis
This thesis describes the application of hyperspectral imaging (HSI) as a novel technique for the analysis of spectral data derived from image analysis of tablet breakdown during dissolution. Whilst defining the rate of release is the common output from traditional dissolution experiments, the …

Active hyperspectral imaging of chemicals on surfaces
Active hyperspectral imaging (HSI) is a promising technique for the detection of chemicals at standoff distances. In active HSI, a target is illuminated by a laser source at many different wavelengths and a camera obtains an image of the illuminated scene at each wavelength. In this research, the …

Ground-Based Hyperspectral Imaging and Data Analysis for Near-Vertical Outcrop Surfaces
… studies in greater detail. Until recently, the hyperspectral data used in geology were acquired mostly from airborne platforms along with some from spaceborne platforms. Due to nadir-viewing geometry, however, these data fail to provide an adequate viewing angle for near-vertical outcrops which …
